Definitions

  • either the axis of the reel must be kept high enough to permit the fingers of the reel to clear the cutterbar in its maximum upper position resulting from the flexing thereof and under which the reel is not able to sweep the cutterbar clean, or the reel must be run at a lower elevation relative to the cutterbar, and under such circumstances, run the risk of the fingers of the reel engaging the higher portions of the flexible cutting bar.
  • the present harvester art has examples of the employment of hydraulic means to control the height of a reel relative to the cutterbar of the harvester.
  • hydraulic means to control the height of a reel relative to the cutterbar of the harvester.
  • means to control the height of the entire header relative to the ground automatically Examples of this are illustrated in U.S. Pat. No. 3,383,845, dated May 21, 1968, to Hirsch et al. and U.S. Pat. No. 3,886,718, dated June 3, 1975, to Talbot.
  • valve means which preferably comprise solenoid-operated valve means actuated by a circuit connected to a source of electric power, said circuit also including switch means which are actuated by means interconnecting the same to said aforementioned sensing means.
  • Still another object of the invention is to provide said sensing means in the form of a plurality of fingers mounted adjacent the cutterbar and responsive to the contour of a field surface, said fingers being connected by linkage means to said aforementioned switch in a manner to operate the same selectively in one of two directions in order to either raise or lower the reel relative to the cutterbar.
  • Still another object of the invention ancillary to the foregoing invention is to provide switch means being a movable contact member commonly supporting a pair of movable contacts respectively associated with the switch in the circuit for the control means for the header and an additional switch in the control means for the power means by which the header is moved greater distances above the field surface upon which the harvester is operating, said movable switch contact member being arranged to operate override mechanism whereby the switch in the circuit for the power means of the reel first is closed and if the contour of the field surface is such as to require elevation of the header to a position spaced a greater distance from the field, said movable switch member being capable of continued movement to effect a closing of the switch in the control circuit for the power means by which the header is elevated.
  • One further object of the invention is to provide a cutout switch in the circuit for the control means associated with the power means for operating the reel, said cutout switch being operable when, for example, the reel is being elevated with respect to the cutterbar and, simultaneously, the header is being elevated by the power means associated therewith, the cutout switch being operable to limit the amount of movement by which the reel is elevated with respect to the cutterbar.
  • FIG. 1 is a fragmentary side elevation of an exemplary combine harvester having mounted on the forward end thereof a grain header upon which a rotary reel is mounted for automatically adjustable movement thereof toward and from the plane of the cutterbar which extends forwardly from the lower edge of the header, said view also illustrating means for raising and lowering the header relative to the ground.
  • FIG. 2 is a fragmentary, enlarged view showing details of the switch means associated with the control means for effecting elevation of the reel with respect to the cutterbar and the raising of the header with respect to the field surface over which the harvester is operating, said view being a substantially horizontal plan view as seen on the line 2--2 of FIG. 1.
  • FIG. 3 is a fragmentary side elevation of the switch means shown in FIG. 2, as seen on the line 3--3 of FIG. 1.
  • FIG. 4 is a fragmentary side elevation of the switch means as seen at right angles to the side elevation shown in FIG. 3 and illustrating the movable contact of the switch means in engagement with a contact of the upper switch shown in said figure.
  • FIG. 5 is a fragmentary side elevation similar to that shown in FIG. 4 but illustrating the movable contact member in engagement with the contacts of both the upper and lower switches shown in said figure.
  • FIG. 6 is a diagrammatic illustration of a preferred electric circuit and a fluid circuit for power means respectively operable to move the reel with respect to the cutterbar and elevate the header relative to the field surface over which the harvester is operating.
  • FIG. 7 is a modified electric and power circuit associated primarily with the reel of a harvester for purposes of raising and lowering the same with respect to a cutterbar.
  • FIG. 1 there is illustrated therein the forward end of an exemplary combine harvester 10 which pivotally supports a feeder housing 12 and grain harvester 16 on hydraulic lift cylinders 14.
  • the header 16 supports a conventional reel 18, rotatably mounted on axis 20 that extends between a pair of arms 22 which are pivotally connected at the rearward ends thereof on opposite sides of the header to transverse frame member 23.
  • the arms 22 are raised and lowered in unison and the reel 18 therewith, by a pair of hydraulic cylinders 24, each one of which being mounted adjacent an opposite side of the header 16 and having its piston rod end pivotally connected to the midportion of one of the arms 22 with its cylinder end pivotally connected to an upright brace member 25.
  • the reel 18 includes a plurality of parallel spaced bats 26 having pickup fingers mounted thereon which sweep the unserved crop material rearwardly into the cutterbar 28 and then the severed crop over the floor 30 and into the auger 32 therein the severed crop material is consolidated toward the center of the header 16 for introducing the same to the feeder housing 12 which elevates the material to the threshing and separating mechanism within the combine 10 for operation thereon.
  • the cutterbar 28 is conventional and includes a sickle knife which reciprocates along a transverse ledger plate and within a plurality of spaced apart forwardly projecting guards; however, for the sake of brevity, these various conventional components will not be specifically labeled but will be referred to as a complete unit per se.
  • the cutterbar 28 is supported on the forward end of a plurality of transversely spaced apart ground shoes 34 that slide over the surface of the ground during operation of the combine 10.
  • the shoes 34 extend in a fore-and-aft direction, below the floor 30, and are pivotally connected at their rearward end to a transverse frame member 36 that is mounted on vertical supports 38 fixedly attached to the rear wall of header 16.
  • each shoe 34 is connected to frame member 40, extending transversely along and adjacent to the forward edge of floor 30, by a flexible chain 42 which limits the downward vertical movement of the shoes 34 as well as the cutterbar 28.
  • a leaf spring 44 which is pivotally connected at one end to frame member 40 and is bolted at its other end to shoe 34, the purpose of springs 44 is to counterbalance the weight of the cutterbar 28. The amount of counterbalance can be varied by slideably adjusting clamp 46.
  • a transversely extending ramp 47 preferably of sheet metal, spans the gap between the cutterbar 28 and the front edge of floor 30. The front of ramp 47 is hinged to the cutterbar 28 and its rear edge rests on the forward edge of the floor 30.
  • the clearance spacing between the floating-flexible cutterbar and the reel be maintained at a minimum so as to provide for a more efficient harvesting operation.
  • the reel be spaced a large distance above a floating-flexible cutterbar to thereby allow for the flexing and floating movement of the cutterbar such that the cutterbar and reel would never contact or engage one another which would result in damage and costly repairs.
  • the exemplary header 16 is also provided with a automatic header height control which automatically controls the clearance spacing of the header 16 relative to the ground. Since the reel height control and the header height control share a substantial number of the same components and inter-react with one another, they will be described together. It should be further pointed out at this time that the reel height control is not dependent on the header height control and can be used on a header not having a header height control.
  • the means for automatically controlling the height of the reel 18 relative to the floating/flexible cutterbar 28 and the height of the header 16 relatively to the ground basically comprises sensing means, generally indicated by the numeral 48, and switch means, generally indicated by the numeral 50.
  • the sensing means 48 includes a transverse rod 52, extending across the width of header 16, pivotally mounted forwardly of and adjacent to header frame member 40.
  • the rod 52 supports a plurality, corresponding to the number of shoes 34, of transversely spaced-apart downwardly and rearwardly projecting sensing fingers 34.
  • the terminal end of each finger 54 rest on the top surface of a corresponding shoe 34.
  • all of the sensing fingers 54 pivot in unison, either upwardly or downwardly, in conjunction with the upward and downward pivotal movement of shoes 34.
  • an actuating rod 56 is pivotally connected to the terminal end of one of the right outside sensing fingers 54 and extends rearwardly therefrom and then bends upwardly for pivotal connection with the contact lever 58 of the complex switch means 50.
  • the switch means 50 includes the contact lever 58, a support bracket 60, a lower switch plate 62, an upper switch plate 64 and an override mechanism associated with the upper switch plate 62 and generally indicated by the number 66.
  • the bracket 60 is L-shaped having its vertical leg attached to the rear wall 61 of the header 16 and its other leg, projecting rearwardly therefrom, supporting a vertical shaft 68 which is fixed thereto and extends upwardly therefrom. As best seen in FIG.
  • stacked on shaft 68 is a hub 70 resting on the top surface of the horizontal leg of bracket 60, the contact lever 58, a hub 72 which is fixed to the underside of lower switch plate 62 and which is fixed to the shaft 68 by a set screw or similar such means, a hub 74, the upper switch plate 64, a hub 76, one leg of an L-bracket 78 which is part of the override mechanism 66, and a washer 79.
  • the upper switch plate 64 which is part of the reel height control and the lower switch plate 62 which is part of the header height control are both of a trapezoidal shape (only the upper plate 64 can be seen).
  • the upper and lower switch plates 64,62 each support a pair of spaced-apart contact pins 82,84 and 86,88 respectively, the contact pins being in the form of bolts that extend through openings in the plates and are electrically insulated from the respective plates by insulators 89.
  • the upper contact pins 82,84 are spaced closer together than the lower contact pins 86,88, the reason being preferably that the reel height control operates over a more limited range than the header height control.
  • the upper contact pins 82,84 are connected by respective lead wires 90,92 to a solenoid valve 94 for actuation of the reel height lift cylinders 24 and the lower contact pins 86,88 are connected by respective lead wires 96,98 to solenoid valve 99 for actuation of the header height lift cylinders 14 (see FIG. 6 for a diagrammatic representation of the electrical and hydraulic circuitry with only one reel lift cylinder 24 and one header lift cylinder 14 being shown).
  • the contact lever 58 is rotatably mounted on shaft 68, as mentioned earlier, and is of a U-shaped configuration having its lower horizontal leg, as seen in FIG. 3, being of greater length than its upper horizontal leg.
  • the terminal end of the lower leg of the contact lever 58 is connected to the rear edge of support bracket 60 by a biasing spring 100 and the other end of the lower leg, adjacent its vertical portion, connects to actuating rod 56 of the sensing means 48.
  • the contact lever 58 is disposed intermediate the upper and lower contact pins 82,84 and 86,88 respectively, such disposition represents the neutral position of the lever 58.
  • spring 100 maintains a biasing force on contact lever 58 which is transmitted through actuating rod 56 to sensing means 48 to thereby insure that the sensing fingers 54 always remain in contact with the ground shoes 34.
  • the upper switch plate 64 is rotatably mounted on shaft 68 and is provided with an override mechanism 66 which allows limited pivotal movement of plate 64 under a predetermined load.
  • the override mechanism 66 includes the L-bracket 78, as seen in FIG. 2, rod 102, biasing springs 104 and 106, brace 108 and vertical support 110.
  • the brace 108 is fixed to one leg of the L-bracket 78 and is attached by bolt 112 to the base support bracket 60.
  • the vertical support 110 is fixed to the upper switch plate 64 and is provided with an aperature at its upper end for receiving rod 102.
  • L-bracket 78 One end of the L-bracket 78 is rotatably mounted on shaft 68 whereas the other end is connected to the hook end of rod 102.
  • Spring 104 is coiled around rod 102 and is held in a state of compression between vertical support 110 and a pin that extends through the hook end of the rod 102.
  • Spring 106 is also coiled around rod 102 and is held in a state of compression by and between a pin through the other end of rod 102 and the vertical support 110.
  • the override mechanism 66 is common in the art and its operation is easily understood from viewing FIG. 2, wherein it can be seen that the brace 108 maintains the L-bracket 78 in a fixed position relative to base bracket 60.
  • biasing springs 104,106 permit limited pivotal movement of upper switch plate 64 on shaft 68 under a predetermined spring load maintained by the override mechanism 66.
  • FIG. 6 diagrammatically represents the hydraulic and electrical circuitry for these controls (only one of the hydraulic cylinders 14 for raising and lowering the header 16 relative to the ground and only one of the hydraulic cylinders 24 for raising and lowering the reel 18 relative to the cutterbar 28 has been shown; it being understood that a pair of the same are included). Further included in this diagrammatic circuitry is a master switch 114 interposed in the electrical power source line and generally located within the operators station of the combine 10 for turning the automatic controls on and off.
  • the header 16 moves forwardly over the ground with the reel 18 being rotated in a clockwise direction, as shown by the arrow in FIG. 1, to sweep the crop material against the cutterbar 28 for severance thereof and the severed crop onto the floor 30 and into the converging auger 32 wherein the material is conveyed to the feeder house 12 for elevation into the threshing and separating components of the combine 10 for further processing thereof.
  • the transversely spaced pivotal mounted skid shoes 34 slide over the ground, supporting the cutterbar 28 for vertical floating and transverse flexing action wherein the cutterbar 28 follows the contours of the ground.
  • the ground shoes 34 pivot correspondingly, and thus, when any one of the shoes 34 encounters a ridge in the field, the shoe 34 pivots upwardly and when one of the shoes 34 encounters a depression or hollow it pivots downwardly.
  • the sensing means 48 and the switch means 50 operate in response to movement of the skid shoes 34, and since their operation is the same for both upward and downward pivotal movement of the shoes 34, but only in the reverse, then, for the sake of brevity, only the operation of the switch and sensing means will be described in relation to an upward pivotal movement of the shoes 34.
  • Spring 100 maintains a biasing force on lever 58 which thereby insures that the sensing fingers 54 are always in an abutting relationship with the top surface of shoes 34, this is also true when the fingers 54 pivot downwardly along with the downward pivotal movement of shoes 34 when a field depression is encountered.
  • the automatic header height controls are provided with means for overriding or by-passing (not shown in the exemplary embodiment) the automatic controls which enables an operator to instantly raise the header in cases where there is a large obstruction in the field.
  • Such overrides are common and are necessitated by the fact that the hydraulics associated with the automatic controls do not react quick enough to prevent possible damage to the combine. In such situations, the header is generally raised a considerable distance higher than in the case of the automatic controls.
  • the reel height control of the present invention is further provided with a cutout switch 116 which limits the distance the reel 18 is raised. As seen in FIG.
  • the cutout switch 116 includes a contact 118, attached to the right reel arm 22, which engages switch 120 as arm 22 pivots upwardly a predetermined distance.
  • the reel height control circuit (lead line 92) is opened.
  • the reel cylinders 24 are now idle while the header height control still is in operation causing the header 16 to continue to raise. It is felt that the operation of the cutout switch 116 is easily understood from the drawings and therefore no fully explanation will be given.
  • FIG. 7 Shown in FIG. 7, is an alternative embodiment of a switch means 122 for controlling the height of the reel 18 relative to the cutterbar 28.
  • the switch means 122 is substituted for the switch means 50 shown in FIG. 6.
  • the switch means 122 includes a pair of potentionmeters 124 and 126 connected in parallel with a voltage comparator 128.
  • the potentionmeters 124,126 being conventional, are connected to the actuating rod 56. As the rod 56 moves back and forth in response to movement of the sensing fingers 54, the resistance of the potentionmeters 124,126 vary.
  • the comparator 128 compares the signals from the respective potentiometers 124,126 and functions to equalize the signals by energizing the solenoid valve 94 in thus actuating the reel lift cylinders 24 to thereby maintain the reel 18 at a predetermined clearance spacing from the cutterbar 28.
